RONEGN PA100 20,000mAh Power Bank with Built-In Cables and 22.5W USB-C

For travellers who want to charge a phone without packing a separate cable for every device, the RONEGN PA100 combines a 20,000mAh battery pack with four built-in cables. Its USB-C output supports up to 22.5W charging, while the built-in iOS output supports up to 20W, making it a practical option for keeping compatible devices powered while you’re away from an outlet.

If your priority is an all-in-one charging kit, the built-in cables and multiple outputs keep essentials together. If you prefer to choose each cable separately, a conventional power bank may suit that approach better.

How to use it

Connect a compatible phone, tablet or other small electronic device using one of the built-in iOS, USB-C, USB or Micro cables, or use the available outputs to charge multiple devices at the same time. The bank has five outputs and three input options, so you can choose a connection that suits the device or recharging setup. Its digital display shows the remaining battery level in 1% increments, helping you see when the power bank itself needs recharging.

For a travel day, place the slim unit in a bag or pocket and use the attached cables during a commute, airport wait or day away from home. The manufacturer describes it as suitable for airline carry-on use, it should be carried on board rather than packed in checked baggage. To recharge the power bank, use its attached recharging cable or a separate A-to-C or C-to-C cable.

Benefits

Four built-in cable types reduce the need to bring a collection of loose charging leads. The 20,000mAh capacity gives you a portable reserve for phones and other supported small electronics, while the USB-C and iOS outputs provide fast-charging options for compatible devices. Five outputs let you charge multiple devices at once, which is useful when travelling with more than one phone or sharing a charging stop.

The digital battery display makes remaining charge easy to read at a glance. Overcharge and short-circuit protection are also listed among its features. Buyers highlight the range of built-in cable options and the compact, portable size. Feedback on charging speed is mixed, and some buyers report concerns about battery longevity, so individual experiences vary.

What matters most

This model is designed around convenience: a single portable charger with its own cable options, rather than a power bank that relies on a separate set of leads. It supports smartphones and tablets, along with devices such as earbuds and smartwatches, it is not intended for charging laptops. That makes it a useful travel companion for keeping smaller personal electronics charged, rather than a replacement for a laptop power supply.

What to clarify

Can it charge a laptop? No. The manufacturer says it can charge phones, earbuds and smartwatches, but not laptops.

How can I recharge the power bank? Use its attached recharging cable, or recharge it with a separate A-to-C or C-to-C cable.

Can I take it on a flight? The manufacturer identifies it for carry-on use and says it should not go in checked baggage.

Final verdict

Choose the RONEGN PA100 if you want a high-capacity portable charger with multiple built-in cable types, a clear battery-level display and several outputs for travel or everyday use. Its all-in-one format is especially useful when keeping charging essentials together matters as much as having power on hand.
